Geology
Short characteristics of the site: Summary of preliminary results of sedimentological analysis of fluvial deposits NNW margin of Kacanovy is presented. There were recognized fluvial accumulation with the altitudes of the base 305 m a.s.l. The accumulation consist mainly of coarse-grained sandy gravel and sand with trough cross bedding. These coarse subangular to rounded clasts of gravels content quartz, orthogneis, quartzite, graphitic phyllite and mica shist; all rock types derived from Krkonoše–Jizerské hory Mts. Preliminary results of measurements indicate that the main direction of paleocurrents is NE to SW and NW to SE.
